摘要针对一类非线性依赖于不确定参数的半定规划问题,提出了两种保守方法。这些方法适用于一般的非线性参数依赖不一定多项式或合理的。他们是基于一个温和的假设,参数依赖表示为两个凸函数的差异。第一种方法使用常数的参数依赖的界限。边界的优化一般归结为凸非光滑极小化。第二种方法使用参数依赖的界限,一个不太保守的结果。当重心对于参数集是可计算的时,边界的优化是立即的。数值例子说明的方法。
Abstract Two conservative approaches are proposed to a semidefinite programming problem nonlinearly dependent on uncertain parameters. These approaches are applicable to general nonlinear parameter dependence not necessarily polynomial or rational. They are based on a mild assumption that the parameter dependence is expressed as the difference of two convex functions. The first approach uses constant bounds on the parameter dependence. Optimization of the bounds is reduced to convex nonsmooth minimization in general. The second approach uses parameter-dependent bounds for a less conservative result. Optimization of the bounds is immediate when the gravity center is computable for the parameter set. Numerical examples are presented for illustration of the approaches.
